True : South Africa also would have been interested, for high-altitude reconnaissance (to replace Canberras) and long-range bombing (they bought Buccaneer instead)
Australia also would have been interested.
But it was decided in France, not to export them, because of the "nuclear smelling"
For the same reason, Mirage IV were never landing in foreign countries (officially) - they had to wait for nuclear capabilities to disappear in the 90s, to start airshow tours in Europe, as well as Africa and Middle-East operationnal trips.
One of them dropped a nuke for real (July 1966) over the Polynesian test range....
